If your Huaxia credit card receives a credit card consumption reminder abroad, and this consumption is not made by yourself, I suggest you immediately call the bank credit card service hotline to apply for freezing the credit card, and then call the police to collect evidence, and cooperate with the bank and the police station to minimize the loss.
There is indeed a risk that credit cards will be stolen when spending abroad. The most thorough way to prevent the credit card from being stolen is to cancel the original card after returning to China and replace it with a new card with a different number. The new card associated with the original account will not lose consumption points, mileage, etc.
When you use a credit card to spend or swipe your card online, you must pay attention to the bank's WeChat or subscribe to the bank's SMS packages such as "balance change" and "consumption reminder". You'd better use this function when you apply for a credit card. If you don't receive the consumer reminder in time, your credit card is stolen or you find problems after the bill comes out, and then you go to the bank to complain, you may face greater trouble.
